seen in 2010, according to the newly released BP Statistical Review of World Energy, 2012. Oil demand grew by less than 1%—the slowest rate amongst fossil fuels—while gas grew by 2.2%, and coal was the only fossil fuel with above average annual consumption growth at 5.4% Global energy consumption grew by 2.5%
US wind and solar together produced more electricity than coal in Q1 2023, according to a review by the SUN DAY Campaign of data just released by the US Energy Information Administration (EIA). more… The post US wind and solar combined produced more electricity than coal in Q1 2023 appeared first on Electrek.
in 2019 to 5,130 million metric tons (MMmt), according to data in the US Energy Information Administration’s (EIA) Monthly Energy Review. CO 2 emissions from coal fell by 14.6%, the largest annual percentage drop in any fuel’s CO 2 emissions in EIA’s annual CO 2 data series dating back to 1973. CO 2 emissions had increased by 2.9%
The company’s plan to decrease carbon emissions involves the possibility of purchasing low-emissions electricity from power sources such as hydro, wind and solar, as well as its own power generation from renewable sources. Geology and ores of the Udokan copper deposit (review).” In 2021, Udokan Copper invested RUB 764 million (US$11.5
Analysts at the US Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) have developed harmonized meta-analyses of lifecycle greenhouse-gas emissions from coal, wind, solar and other energy technologies. The supplemental issue overall contains 12 meta-analyses and critical reviews of LCAs.
This was the result of accelerating economic activity as well as the combination of higher natural gas prices and colder weather favoring an increase in coal use. This resulted partly from lower electricity demand but also from increases in electricity generation by solar PV and wind.
The process generates H 2 from natural gas or coal through steam reforming and combines it with N 2 , which has been separated from air by a cryogenic process, to form NH 3. annual increase over the next three decades), and global fuels consumption (solid gray, 2018 value taken from the BP Statistical Review of World Energy).
However, the resulting low gas prices, as well as clean air and climate policies, will promote further switching to gas from other more polluting energy sources, such as oil and coal. The pandemic has created disruption in the global energy sector, but low gas prices will ultimately stimulate demand growth as the economy recovers.
Martino Tran and his colleagues reviewed the literature on electric vehicles, with a focus on market diffusion of full battery electric vehicles (BEVs). In their review, they assessed the key interactions between technology and behavior across different scales: system level, local level and consumer adoption. —Tran et al.
Relying on a higher share of efficient, low-emission combined cycle power plants and wind energy could save €150 billion (US$200 billion) by 2030 while attaining the same CO 2 targets, Siemens says. The country should give greater priority to high-efficiency combined cycle power plants and wind power, the company suggests.
However, the two conclude in their review, substantial advances in catalyst, electrolyte, and reactor design are needed to enable CO 2 utilization via electrochemical conversion a technology that can help address climate change and shift society to renewable energy sources. Current research efforts in the electrochemical conversion of CO 2.
Global energy investment stabilized in 2018, ending three consecutive years of decline, as capital spending on oil, gas and coal supply bounced back while investment stalled for energy efficiency and renewables, according to the International Energy Agency’s latest annual review.
A new report from the National Research Council examines and, when possible, estimates, “hidden” costs of energy production and use—such as the damage air pollution imposes on human health—that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them. cents per kWh.
Between 2010 to 2030 the contribution to energy growth of renewables (solar, wind, geothermal and biofuels) is seen to increase from 5% to 18%. Natural gas is projected to be the fastest growing fossil fuel, and coal and oil are likely to lose market share as all fossil fuels experience lower growth rates. Coal will increase by 1.2%
A Federal Quadrennial Energy Review. Burning natural gas is about one-half as carbon-intensive as coal, which can make it a “bridge fuel” for many countries as the world transitions to even cleaner sources of energy. DOE will take comment on the draft solicitation, with a plan to issue a final solicitation by the fall of 2013.

The bp Statistical Review of World Energy is a venerable survey of the world’s energy production and consumption — the oil giant has been publishing it yearly since 1952. It’s an extremely detailed report — it lists the amounts of energy generated and consumed, as well as the means of generation, for just about every country […].
The authors highlight three possible strategies for CO 2 conversion by physico-chemical approaches: sustainable (or renewable) synthetic methanol; syngas production derived from flue gases from coal-, gas- or oil-fired electric power stations; and photochemical production of synthetic fuels.
Continuing substitution of gas for coal (and in some instances for oil) will remain an effective short- and middle-term decarbonization measure and an economic boon only insofar as methane leakage from production and transport is held to low levels and drinking water is not adversely impacted, PVCAST noted.
Weather observations such as wind speed and direction (with other evidence) allowed researchers to identify plumes of polluted air from the Beijing urban area and population centers to the south, as opposed to relatively clean air arriving from the north. The combustion of outmoded industrial processes can fall somewhere in the middle.
Newly installed solar photovoltaic (PV) capacity in the US in 2014 reached a record 6,201 MW, growing 30% over 2013’s total, according to the new US Solar Market Insight 2014 Year in Review report released by GTM Research and the Solar Energy Industries Association (SEIA). The additions are dominated by wind (9.8 GW), natural gas (6.3
Carried long distances across the country by wind and weather, power plant emissions of sulfur dioxide (SO 2 ) and nitrogen oxide (NO x ) continually travel across state lines. The CSAPR limits emissions from upwind states’ coal- and natural gas-fired power plants, among other sources. Earlier post.).
A year ago I published an assessment of a quite remarkably bad, unpeer-reviewed paper by one of the Geological Survey of Finland’s (GTK) associate professors, Simon Michaux. The paper’s quite risible conclusions were that there wasn’t nearly enough metal in the ground to be able to electrify everything with renewables.
For onshore leases, the review found that approximately 45% of all leases and approximately 57% of all leased acres are inactive. That’s why I’ve requested a comprehensive safety review by the Nuclear Regulatory Commission to make sure that all of our existing nuclear energy facilities are safe.

Between now and 2030, annual wind additions need to more than double compared to 2024 levels.
Photo by Los Muertos Crew on Pexels.com Solar capacity additions hit the ground running in 2024, pushing renewables’ installed generating capacity past coal, according to new US Federal Energy Regulatory Commission (FERC) data. That’s more than the installed capacity of coal (207.15 of the total. GW) but also hydropower (101.41
Vulcanol is CRI’s brand name for renewable methanol, produced from CO 2 and hydrogen from renewable sources of electricity (hydro, geothermal, wind and solar). Methanol can be produced from a range of renewable sources and fossil-fuel based feed-stocks; in practice methanol is mainly produced in coal-rich China from coal.
Of those, approximately 180 full applications were encouraged, and 37 final awardees were selected through a rigorous review process with input from multiple review panels composed of leading US science and technology experts and ARPA-E’s program directors. More than 540 initial concept papers were received in the three focus areas.
In the US, a combination of demand reduction and displacement of coal-fired power by gas-fired generation is the lowest cost way to reduce CO 2 emissions by up to 50%. At least for the near term, that would entail facilitating energy demand reduction and displacement of some coal generation with natural gas.
Some of the collected tax money will fund investments in clean technologies such as solar, wind and geothermal—an estimated A$100-billion worth of investment in renewable over the next 40 years, Gillard said. The Government is also separately investing in protecting jobs in the steel and coal industries.
Photo by Amol Mande on Pexels.com Solar and wind now make up more than 20% of total US electrical generating capacity, according to new data from the Federal Energy Regulatory Commission (FERC). The renewable energy mix – biomass, geothermal, hydropower, solar, and wind – is now nearly 30% of total US electrical generating capacity.
Solar is predicted to surpass hydropower within the next few months to become the second-largest renewable energy source behind wind. Electrical production by hydropower and wind showed signs of recovery in Q1, following significant declines in 2023. Wind was still down 2.8% Small-scale solar accounted for 31.5% vs. 11.6%).
of capacity added, marking the seventh consecutive month that it provided more new generating capacity than any other energy source, according to the US Federal Energy Regulatory Commission’s (FERC) latest monthly “Energy Infrastructure Update” report (with data through March 31, 2024), which was reviewed by the SUN Day Campaign.
The UK has been a leader in deploying on and offshore wind turbines. What we have not done so well is to ensure that we have a solid base level of generation to supply electricity when there is no sun and no wind. At the time of writing, mid-morning 21 Sept, we have: Wind 9%. OfGem review the price cap every six months.
power from renewable sources—wind, solar, geothermal, biomass or landfill gas, hydropower, and marine and hydrokinetic—for retail electricity suppliers beginning at 6% in 2012 and gradually rising to 25% in 2025 and continuing at that level through 2039. The draft establishes a Renewable Portfolio Standard—i.e., Clean Fuels and Vehicles.
When it comes online in 2026, Linglong One will have a capacity of 125 megawatts of electricity (MWe)—equivalent to around 40 onshore wind turbines. Even more discouragingly, nuclear’s per-unit cost increased 26 percent between 2009 and 2019—while solar and wind power prices plummeted instead.
Photo: Openverse Renewables – solar, wind, biomass, geothermal, hydropower – are now 30% of total US electrical generating capacity, according to analysis of FERC’s mid-year data. During the first half of 2024, solar and wind added 13,072 MW and 2,129 MW, respectively. For seven of those 10 months, wind took second place.
of the total) and should surpass it within the next few months to become the second largest renewable energy source, behind only wind. Similarly, the mix of solar (5.6%) and wind (10%) is closing in on coal (15.9%) and seems well-positioned to overtake the fossil fuel this year. drop in power from wind turbines as well as 5.9%
These zoning decisions blow in whatever direction the development winds are gusting in the city at the moment and there is no consistency, logic or equity in the decisions made. And do you wind up offering your customers some kind of assistance in filing the rebate form? THE HOLY GRAIL OF SOLAR: $3 A WATT, CHEAPER THAN COAL.
Solar also provided nearly 100% of all new generating capacity in August, according to the SUN DAY Campaign, who reviewed the FERC data. What’s more, renewable energy sources – biomass, geothermal, hydropower, solar, wind – accounted for over 90.1% Solar and wind now make up 21% of US generating capacity. Renewables were 99.8%
Then, in 2009, I was recruited into Google’s effort to make renewable energy cheaper than coal (an initiative we called RE While that last project didn’t pan out as hoped, I learned a lot from it. Decades later, there had been no confirmations in credible peer-reviewed journals. So, case closed. Or perhaps not.
The source of the electricity – whether renewable sources like wind, solar, or water, or nonrenewable sources like coal – is also important. ones that burn coal) still see a significant amount of emissions from workplace EV charging. A company that wants to reduce CO2 emissions should review its upstream emissions.
Solar and wind are clearly now the cheapest form of electricity. The challenges posed by solar and wind generators are real. They are inherently variable, producing electricity only when the sun is shining and the wind is blowing. But limits to these technologies can undermine the case for a renewables-only electricity mix.
